Caution

We strongly recommend that all Neptronic® products be wired to a separate transformer and that transformer shall service only Neptronic® products. This precaution will prevent interference with, and/or possible damage to incompatible equipment.
When multiple actuators are wired on a single transformer, polarity must be observed. Long wiring runs create voltage drop which may affect the actuator performance.

Mechanical installation

Mounting of the actuator on valve

1. Screw completely the valve shaft (C) unto the coupling of the actuator (A).
2. Unscrew the coupling (A) for ½ of turn in order to leave a functional play.
3. Screw the counter nut (B).

Warning:
Do not over tight coupling of the actuator on the shaft of the valve.

Mounting of the actuated valve on system

• Vertical mounting

• Horizontal mounting

1. Pay attention to system particularity; be sure that the expansions, contractions of the system and its medium as well as operating pressures are within the tolerances.
2. When plumbing, the motorized valve should be situated in an easily accessible place and sufficient space should be allowed for the removal of the actuator.
3. To prevent moisture from collecting in the motor casing, install the motorized valve such that the actuator is superior to the valve, at 20-30º / at vertical. Avoid mounting the valve so that the valve stem is below horizontal.

Wiring Diagrams

Analog or PWM

• **Digital – 3 wire / 2 position

**

• Digital – 4 wire / 3 point floating

Special consideration for Digital control
In this mode, the actuator is sensitive to induced electrical voltages from external sources. To prevent such interference, if the signal on pins 4 and 3 on TB1 are from an external 24 Vac source, install a resistor 2.2kohm, 0.5W between pins 4 and 1 and another of 2.2kohms, 0.5W between pins 3 and 1 of TB1. These resistors are included.

Input Signal and Feedback setup

• DS1-3 at OFF = 2 – 10Vdc (default setting)
• DS1-3 at ON = 4 – 20mA

| Feedback is set with Dipswitch #4

•  DS1-4 at OFF = 4 – 20mA (default setting)
• DS1-4 at ON = 2 – 10Vdc

Digital & PWM Mode| No Input Signal Setting
DS1-3 MUST be at OFF

PC Board

Dip switch settings

Stroke adjustment

No control signal change

1. Apply power and, WAIT FOR LED TO BE OFF (around 10 seconds).
2. Press and release the reset button to start the auto-stroke process.
   The LED should be illuminated.

• First option :
  The actuator will then travel in both directions to find its limit and position itself according to the demand.
  The LED will extinguish, the process is complete.

• Second option:
  When the desired end position is reached, press and release the reset button. The actuator will now go the start position. (you can also press and release the reset button when It’s reaches the start position) The LED will extinguish, the process is complete.

Programming

Change of control signal

1. Remove power and put all dip switches “OFF” (Default).
2. Apply power and, within 10 seconds, press and release the reset button. The LED should be blinking.
3. Select the control signal with dip switches:

 | Digital or Analog Modes| PWM Mode refer to PWM Mode section below to program in this mode.
---|---|---
Move switch No1 “ON” and then “OFF”.| Digital (On/Off or 3 point floating)| Set 5s pulse (Default)
Move switch No2 “ON” and then “OFF”.| Set 25s pulse

Stroke adjustment
see the stroke adjustment section above.

PWM Mode & Speed selection

To enable or disable the PWM mode on the actuator, do as follow:

1. Remove power from the actuator
2. Jump pin 3 & 4 of J3 (instead of 4 & 5)
3. Select the desired action using the dipswitches (DS1):
   DS1-1 DS1-.2 DS1-1| DS1-.2|
   ---|---|---
   OFF| OFF| 90 sec. ½”
   OFF| ON| Enable PWM Mode
   ON| OFF| Disable PWM Mode
   ON| ON| 90 sec. 1”
4. Power on the actuator
5. Wait 5 seconds
6. Remove power from the actuator
7. Change jumper position from J3 3 & 4 to 4 & 5.
8. Re-apply power supply to actuator PWM is factory preset at 5 sec. pulse, refer to Programming section above to change pulse setting.

Zero and span calibration

This feature is applicable to analog control signal only.

1. Remove power and put all dip switches “OFF”. (factory preset).

2. Apply power and, within 10 seconds press and hold the reset button until the LED blinks once.
   The Zero and span calibration process then start.

3. Release the reset button. The LED is now constantly illuminated.

4. Apply new minimum voltage.
   It can be any value between 0 to 7 Vdc, with an external 0 to 10 volt supply (ex : MEP).

5. Press and release the reset button to memorize the new minimum voltage. The LED blinks.

6. Apply new maximum voltage.
   It can be any value between 3 to 10 Vdc, this value should be greater than the new minimum value.

7. Press and release the reset button to memorize the new maximum voltage. The LED blinks.
   The Zero and span calibration process is complete.

Note: To reset zero and span to 2 to 10 Vdc (factory value). You just have to re-select the analog control signal mode, see Programming.
